class City {
public String screamingInNewYork() {
return "SexAndTheCity";
}
}
 
class Town extends City {
System.out.println(this.screamingInNewYork());
}
 
/*
 
---------- Javac ----------
Town.java:8: <identifier> expected
System.out.println(this.screamingInNewYork());
                          ^

Now My Question...

class City {
public String screamingInNewYork() {
return "SexAndTheCity";
}
}
 
class Town extends City {
public void greeting() {
System.out.println(this.screamingInNewYork());
}
}
/* NO Compiler Error */

Please Explain???
Thank You For Your Time...

because you are not able to call a function within a class and out of a function declaration !

within a class you are able to declare functions, vars .... but not to call a function, you have to call a function within a function declaration!

Hi,
Your statement (System.out.println) must be inside a method.
You just can declare and initialize class variable and instance variable at that place.
You can learn about that in the Java Language Specification

Correct me if i am wrong...

thanks

I dont know where to look specifically in JLS
but i am assuming that you cant write System.out.println ina class ...
you need to have that in a method...

class X{ System.out.println("hi");} 
/* error*/

and

class X{
 void print() {
System.out.println("hi");
}
} 
/* compiles perfectly*/

if somebody can shed more light, i would be grateful...
regards

You can indeed not have any code outside a method or initializer block.
The one exception to this are calls to new to initialize objects, and those calls can only contain literals as arguments if I'm not mistaken.
